[Dovecot] dovecot auth feature request

[Frank Cusack]

when i try to run dovecot for SASL support only, with literally just
this configuration:

protocols = none
ssl = no
auth default {
  mechanisms = plain login

  passdb passwd-file {
    args = /etc/dovecot/passwd
  }

  socket listen {
    client {
      path = /var/spool/postfix/private/auth
      mode = 0660
    }
  }
}

I get this:

Error: ssl_cert_file: Can't use /etc/ssl/certs/dovecot.pem: No such file or 
directory

Since, in this configuration, SSL doesn't have meaning, dovecot shouldn't
be looking for any cert file.  Easily fixed with "ssl = no" but  that
shouldn't be required.
